Stratovolcano

Khangar volcano is located in central Kamchatka. It is the southernmost volcano of the Sredinny Range with a 2 km-wide lake filled caldera.
A large explosive eruption 6900 years ago produced 12-15 cubic km of tephra.

Khangar caldera formed 38,000-40,000 years ago.

A large deep earthquake (magnitude 7.3) occurred 200 km SW of the volcano on 24th November 2008. The earthquake epicentre was at a depth of 487 km.

Eruption 6460 years ago
The summit of Khangar volcano contains a 2.5 x 2 km wide crater which was formed in a subcaldera eruption about 6460 + 135 years ago. The eruption produced dacite pyroclastic deposits, including tephra and pyroclastic flows, with a volume of over 10 cubic km.
